Title: Improvements in servo-assisted brake systems
IPC: B60T13/10
Filed: 1964-09-28
Abstract: 1,127,012. Brake transmitting mechanism. COMMER CARS Ltd., and E. G. V. GILL. 27 Sept., 1965 [28 Sept., 1964], No. 39446/64. Headings F2E and F2F. In a servo-assisted braking system of the kind in which initial movement of a control member (e.g. a hand brake lever 10) causes operation of a servomotor 11 for each wheel through actuation of a valve 14 to effect application of the brakes, further movement of the control lever maintaining the -brake ap- . plication through mechanical connection means, a one-way clutch device in the form of a pawl and ratchet device 25, 22 permits the brakes to be applied under servo action independently; of further movement of the control member and enables further movement of the control member to become operative through the device, applies braking effort without first taking up lost motion. Consequent upon the operation of the servomotors 11 movement of the lever 13 is transmitted back through a link 18, cross shaft 19 and link 20 to a ratchet quadrant 22 which is rotated freely to a position shown in chain dotted lines. An arm 24 is pivotable at its upper end about the centre of the (quadrant and at its lower end is pivoted to a pawl 25 to which a link 16 is attached. After the initial movement of the-hand-brake lever 10, the servo-, motors 11 'operate to apply the brakes and at  the same time they rotate the quadrant 22' without transmitting any movement to the lever 10. Further movement of the lever 10 transmits effort to the rod 16 to cause the pawl 25 to engage the quadrant 22 so that the whole pawl and ratchet unit will fulcrum about -pivot 31 to transmit the applied effort, through the ratio of multiplication, to the remaining linkage and the brakes. An abutment 35 is provided on the. quadrant 22 so that the pawl will engage the -quadrant if the servo-mechanism fails.

Abstract: 894,558. Cold separation of gas mixtures. LINDE'S EISMASCHINEN A.G. GES. FUR. Dec. 10, 1958 [Dec. 11, 1957], No. 39845/58. Class 8(2). Continuous purification of a gas mixture e.g., hydrogen and deterium prior to rectification in a column 2 is effected in cyclically operating regenerators RI, RII, RIII each of which serves in turn three purposes firstly to freeze out impurities from the crude gas stream A having previously traversed a heat exchanger 3 and a nitrogen evaporator 6 and conventional change over valves a, secondly to re-evaporate the condensed impurities by a reverse flow of cold scavenging gas stream A<SP>1</SP> viz. pure hydrogen withdrawn through changeover valves b from the effluent gas conduit 22 of the column 2; the stream A<SP>1</SP> being in countercurrent flow to an auxiliary porous hydrogen current B 1  issuing from a compressor 10 through an adsorber 11, the nitrogen evaporator 6, a duct 12, a change-over valve 13 and a coil QII, and thirdly to provide a heat balance stream B<SP>1</SP> which is withdrawn from duct 22 and passed reversely through the regenerator to compensate for the heat introduced by the warm compressed hydrogen stream B 1  during the second of the three periods of operation. Thus when the first of the three cycles has been completed change-over valves a, b, 13 are operated and regenerator RIII is used to condense out the impurities from gas stream A, RI is subjected to scavenging gas stream A<SP>1</SP> and the counterflowing warm hydrogen stream B 1  and RII is subjected to the heat balance stream B<SP>1</SP>. During the third cycle RII serves to condense inpurities from the crude gas stream A, RIII is traversed by the scavenging stream A<SP>1</SP> and the counterflowing warm hydrogen stream B 1  and RI is traversed by the heat balance stream B<SP>1</SP>. In a modification a fourth regenerator between RII and RIII when subjected to their cooling phases is scavenged by gas under vacuum.

Title: Device for measurement of water level
IPC: G01F23/26
Filed: 1967-09-04
Abstract: 1,203,452. Selective signalling. VIZGAZDALKODASI TUDOMANYOS KUTATO INTEZET. 4 Sept., 1967 [28 Sept., 1966], No. 40405/67. Heading G4H. Liquid level is measured directly in digital form by an array of electrode pairs interconnected by diodes, the electrode pairs being progressively immersed as the liquid rises. In the preferred embodiment. Fig. 2, a three-bit monophylic binary output 11, 12, 13, is produced. The principle or operation can be seen from the least-significant bit array (right-hand column). When the water 10 covers the two electrode pairs 4a1, 5a1, as shown, current will flow from the positive terminal 1 via both electrode pairs in series and back to the negative terminal 2, producing a certain potential at the output terminal. However, when the water is lower, for example between levels 3 and 4, the electrode pair 4a1 is not immersed, no current flows and a different potential is produced at the output terminal. The monophylic output from the array shown in Fig. 2 may be converted into a corresponding number of pulses (Fig. 3, not shown) by applying clock-pulses to a monophylic counter until its output is the same as the liquid level output.

Each sequence control word contains a field (the left hand field in Fig. 1) by means of which a corrresponding microprogram routine is accessed. The right hand field contains an address, in the form of two four bit hexadecimal characters, which is used to access the next control word. Four interrupt leads are provided giving sixteen combinations and the interrupt signals are OR-ed with bits of the right hand address character. The resulting address is used to access the next control word by doubling and adding one, the address of each control word being shown above the corresponding word in Fig. 1. The arrangement may be used in time sharing systems where each machine cycle is divided, in this case, into sixteen, the particular sequence of control words depending on the state of the interrupt signals. The programs selected by the control words may relate to I/O devices sharing a common program store. The interrupt signals may be generated within the system or externally, e.g. by I/O devices requiring service.

Abstract: 1445834 Automatic voltage control LUCAS ELECTRICAL Ltd 14 Aug 1973 [5 Sept 1972] 41065/72 Heading G3R [Also in Division H2] A battery charging system comprises an alternator having a field winding 45, the opposite ends of which are coupled by transistors 44, 46 to output lines 15, 17, and diodes 47-49. When an ignition switch 19 is closed, a warning lamp 18 is illuminated and a transistor 25 is switched on which in turn switches on the transistors 35, 44, 46. Current therefore flows through the field winding 45 until the battery voltage increases sufficiently to cause conduction of a transistor 26. The transistors 25, 35, 44, 46 are therefore switched off to prevent current flow through the winding 45. The diodes 47, 49 enable the current in the winding 45, when the transistors 44, 46 are switched off, to charge the battery 10. A protective Zener diode 51 breaks down if the potential between the lines 15, 17 becomes excessive.
